, This-invention relates" to a gun sight or sight fattachment for a firearm and has for its pr mary object to detachably and adjustably mount a novelly constructed sight attachment on the barrel of a firearm.

A further object of this invention is to eliminate blur or distortion of a target by providing a novelly constructed sight tube, which will enable a rifieman to accurately and positively fix in various inclined planes with respect to a horizontal plane.

These and ancillary objects and structural features of merit are attained by this invention, a preferred embodiment of which is set forth in the following description and illustrated in the accompanying drawings, wherein:

Figure 1 is a side elevational view of a conventional rifle, illustrating the sight device, constructed in accordance with the principles of this invention, attached thereto in a manner as taught by this invention;

Figure 2 is a vertical longitudinal section on an enlarged scale of the front ends of the sight attachment;

Figure 3 is a vertical longitudinal section of the rear end of the sight attachment;

Figure 4 is a transverse section on line 44 of Figure 3;

Figure 5 is a transverse section on the line 5--5 of Figure 2;

Figure 6 is an enlarged detail view on the line 6--'6 of Figure 2;

Figure 7 is an enlarged detail view on the line 1-1 of Figure 2, and,

Figure 8 is a front elevational view of the clamping means for supporting the rear end of the sight attachment.

The numeral l0 designates a conventional firearm, such as a rifle, which includes a stock l2 anda barrel II. The barrel I4 is formed with a conventional upstanding front sight i6 and an upstanding, vertically adjustable rear sight l8. A:sight attachment 20, constructed in accordance with this invention, is adapted for detach- 2 Claims. (01. 33-50) able and adjustable positioning on the barrel, the sight attachment including an elongated tube 22. The tube is formed, adjacent its front end, with a longitudinally extending V-shaped slot 24, within which is slidably disposed the front sight l6. A U-shaped resilient clamping member 26 is concentrically disposed about the front end of the barrel, behind the front sight I 6 and is formed with unattached opposed ends 28 and 30 which are inturned above the barrel as at 32 and 34, whereby the member 26 is clamped on the barrel, with the sections 28 and 30 being outwardly bowed and extending upwardly and outwardly from the barrel. The tube is formed with laterally extending lugs 36 and 38 which are adapted to be disposed through transverse openings formed in the opposed sections or legs 28 and 30, whereby the front end of the tube is securely cradled within the clamping member 26.

The front end of the tube is formed with longitudinally extending opposing slide-ways 40 and 42 and a flanged cup or cap is adapted to be secured on the front end of the tube, the cap being formed with spring clips 44, which are adapted to slidingly clamp in the slide-ways. The cap 46 is formed with a transparent open end 48, within which is disposed a sighting element 50, such as a cross hair.

A band 52 is disposed about the rear end of the tube and the stock l2 and is formed with a catch 54, whereby the same may be locked about the tube and stock to retain the rear end of the tube on the rear end of the barrel. The catch 54 includes a pair of pivoted members 56 carried by one end of the band and a locking member 58 carried by the other end and adapted to receive the pivoted members 56. A spring 60 is vertically disposed between the barrel and'the tube 22, so that the tube is resiliently mounted at its rear end on the barrel, the spring 60 functioning to urge the rear end of the tube upwardly from the barrel. An adjusting screw 62 is vertically disposed in the upper end of the band, a locking nut 64 being secured to the upper end of the band for retaining the screw in adjusted positions. A saddle plate 66 is formed on the lower end of the screw and is adapted to bear on the tube 22 above' the spring 60. The adjusting screw 62 thereby retains the rear end of the tube 22 in adjusted positions on the spring 60, the screw 62 counteracting the resilient urging of the spring.

It can thus be seen that the tube may be easily positioned on the barrel by placing the tube on the barrel so that the front sight I6 is received within the opening or slot 24 and the lugs 36 and 38 are inserted in the openings in the legs 28 and 30 of the clamping member 26. The band is then disposed about the stock and rear end of the tube and is locked thereon by the catch means 54. The screw 62 is then adjusted to position the rear end of the tube in the desired angular position, the rear end being easily raised and lowered by the adjusting screw and spring.

It is to be particularly appreciated that the sight tube is easily attached to a conventional firearm, the attaching thereof requiring no alteration of the firearm and eliminating the necessity of employing tools. Further, it can be appreciated that the tube is in effect pivotally mounted on the barrel by means of the lateral lugs carried by the front end of the tube, which are inserted in the openings in the upstanding leg sections of the clamp. Thus, as the rear end of the tube is raised and lowered by the adjusting screw and spring, the lugs act as axes about which the front end of the tube pivots in a vertical swinging position. The adjusting means carried by the back clamp allows the rear end of the tube to be elevated into the proper position to lower or raise the sight tube to vary the target range. All of the adjustmentsof the tube, as well as the attachment and detachment thereof on a rifle, require very little time and necessitate little skill.

However, since many other purposes and objects of this invention will become apparent to those skilled in the art, it is to be understood that limitation is only sought in accordance with the appended claims.

Having described the invention, what is claimed as new is:

1. A sight attachment for a firearm including a barrel and a front sight; comprising an elongated tube having a slot adjacent its" forward end accommodating the front sight, a substantially U-shaped resilient bracket having spaced legs connected by a Web portion, oppositely projecting pivot pins carried by said tube on opposite sides thereof, each of said legs having an opening pivotally receiving one of said pins, said legs being convergent thence divergent between the web portion and the openings for partially embracing a barrel and spacing the tube from the barrel, said bracket being sufilciently resilient to permit spreading of the legs to free the pins from the openings and to remove the bracket from the barrel, and a combined means spaced longitudinally of the tube from the pivot pins for securing the tube to a barrel and also for adjusting the tube relative to the barrel.

2. In a firearm including a stock supporting a barrel havingafront sight, a s ighting device comprising a tube supported on the barrel and havin a slot accommodating the front sight, said front sight extending radially upwardly into the tube through the slot, a forwardgqlanipjg lnjhg the forward end of the tube to the Barrel, and a'rear clamp securing the rear end of the tube to the barrel, said rear clamp comprising a flexible band including a catch whereby the band may be locked about the tube and stock and a fastener adjustably carried by the band and engaging the rear end of the tube, and spring means interposed between the rear end of the tube and the barrel and urging the tube against said fastener.
